. Find sets of parametric equations and symmetric equations of the line through the point parallel to the given vector or line (
omeli [17]

Answer:

a) L(x,y,z) = (-4,0,2)+(2,8,-7)*t

b) (2-z)/7= y/8=(x+4)/2 (option B)

Step-by-step explanation:

the parametric equation of the line passing through the point P₀= (-4,0,2) and parallel to the vector v=2i + 8j - 7k is

L(x,y,z)=P₀+v*t

therefore

L(x,y,z) = (-4,0,2)+(2,8,-7)*t

or

x=x₀+vx*t = -4 + 2*t

y=y₀+vy*t = 8*t

z=z₀+vz*t = 2 -7*t

solving for t in the 3 equations we get the symmetric equation of the line:

(2-z)/7= y/8=(x+4)/2

thus the option B is correct

Find the functional values g (-3), g (0), and g (5) for the compound function.
Zinaida [17]

Answer:

g(-3)=7

g(0)=7

g(5)=\dfrac15

Step-by-step explanation:

g(x) =\begin{cases}7 & \text{if } x \leq 0 \\ \\\dfrac{1}{x} & \text{if } x > 0\end{cases}

This means:

  • when x is equal to zero or less than zero, g(x) will always be 7.
  • when x is more than zero, g(x) is \frac{1}{x}

\implies g(-3)=7

\implies g(0)=7

\implies g(5)=\dfrac15
